Agreed, That is the worst one of the batch. A needle is the only way. I also have brass picks and reverse tweezers, they clamp when you release them. Good old Amazon.
Thanks for the tip. Unfortunately, I couldn’t get the needle to bite long enough to get leverage on the o-ring unseat it from it’s position. Looks like I’ve got a new project for the weekend!
I’ll have to find some decent picks. The ones I have (or had) were great but wouldn’t fit in that opening - ended up breaking them and now they’re nothing more than some short chopsticks
I took it apart to check everything I could. I found a few o-rings that seemed dry and discovered differences in the reg’s - the first had the upgraded brass piston, but the second still had the black plastic piston one. I ended up getting a full reseal kit from Huma-Air, and a few other things, so I could get everything in tune with one another.
Brass picks, 0-ring, Amazon. A nice small dental pick will work down for that ^&%$#@ one that is buried but caution must be used.
I got replacement reg’s from Huma, made that switch much easier. My tank doesn’t have a valve (it’s hooked into the bottle adapter). I was thinking about getting another one of those to have a second tank, but I’m likely going to get a buddy tank at some point.
Normally I can knock off a reg in under 30 min, my friends took me close to 2 hrs because of that Y&^%$#@$%^&Y^%$ 0-ring down there. Hard to see, if they are old they are flush with the bore and hard.
Considering it’s my first PCP, I’m actually surprised at how easy and straightforward everything has been, besides the
o-ring. Frankly, I’m more worried about tuning once I’m done with this maintenance.Honestly, I wouldn’t rule it out. I intentionally bought a used gun so I could learn the mechanics. I considered others PCPs first, but after shooting a few different FX models, I can say they felt different (in a better way). Aside from this one o-ring, it’s actually quite easy to work on. I opted for the FX Maverick as it’s not as intensive as the M3 (at least that was my perspective).
All airguns have their quirks, because FX sells a heck of a lot of guns more issues come to the surface. Mavericks aren't too bad to work on. Now that I've got the regulator issues sorted out they've been rock solid. Tuning is 'easy', once you know the keys and a certain amount of luck.
Any advice on finding the “keys” to tuning? I was hoping to set reg’s and then adjust power wheel to dial-up down between 26 gr pellets / hybrid slugs and 34 gr pellets…
What is your barrel length? In my experience you can kind of tune for two different weights but its not the best. If you dont mind keeping your heavier 34g at normal pellets speeds like ~880fps and your lighter 26g at "too fast" like 980fps you might be ok. You end up getting some erratic ES if you try to use the power wheel to tune down too far, but within reason it can work out well. So I would tune for the 34g and get those dialed in and then leave the regs/IHS alone and play with the power wheel only. You will probably need to pick one or the other for optimal accuracy. Pellets dont usually like to be pushed too fast and do some really strange things in flight.
Barrel length is 700. I know there are different target ranges for reg’s and PW / HS for different ones and wasn’t sure if there was a way to find some balance between the two. Figured it was worth a shot. I know the settings it was at, 150 / 120 (not sure about the PW though), it was shooting the 34g pellets pretty damn well at 50-75 yards.
